What to Do When There Is Fog Inside the Car on a Rainy Day?
2 Answers
Here are some solutions for fogging inside the car on a rainy day: Turn on the air conditioning cold air: Direct the air vents toward the windows, set the fan speed to maximum, and lower the temperature to remove the fog inside the car. Open the windows diagonally inside the car: This helps in defogging. Use a defogging spray: Prevents water vapor from condensing on the glass, and one application can prevent fogging for about ten days. Below are some precautions for driving on rainy days: Maintain a sufficient safe distance. Use the lights correctly. Avoid slamming on the brakes, accelerating too hard, or making sudden steering wheel turns.
As a long-distance driver, I often encounter fogging inside the car on rainy days, which is really annoying. My experience is to immediately turn on the air conditioning for defogging, set to external circulation and cold air mode—the fog usually clears within minutes. Never switch directly to warm air, as the temperature difference can make the fog worse. On rainy days when you can't open windows, air conditioning is the most reliable solution. Keeping a defogging cloth or spray in the car also helps—just spray and wipe the inside of the windshield. Why does fogging happen? High humidity on rainy days combined with temperature differences between the inside and outside of the windows causes condensation. Safe driving requires clear visibility, so taking time to defog before driving is absolutely worth it. With over 20 years of driving experience and zero accidents, I credit these small but crucial habits. Before the rainy season, I always check the air conditioning system to ensure optimal dehumidification performance.
